Question

if one angle of /_ABC is of 90⁰ then what will be the sum of other two angles of a triangle?​

Answer 1

We know,
Sum of all angles of a triangle = 180 degrees

Given-
One angle = 90 degrees

Let this angle be x
Other two angles be y and z respectively

Thus,
180 degrees = x + y + z
180 = 90 + y + z
y + z = 90 degrees

Therefore, sum of other two angles of a triangle is equal to 90 degrees.
